Grid Tied or Grid Connected Solar PV System is connected to the utility grid and allows the consumer to use solar energy as well as electricity from the grid. This System could either be Rooftop mounted or Free Field Installations based on the size and capacity.

When the sun radiation falls on the solar cells they generate electricity in the form of Direct current (DC). The Grid Connected Inverter converts the direct current (DC) into Alternating current (AC) that is used to power the load through the Distribution Board (DB).

With Grid Connected there are two situations:

  • When the generated solar power is less than the load, then the grid supplies additional power to the load.
  • When the generated solar power is more than the load, then the surplus power is exported to the grid.

In both the situations, the Net Meter records the exported solar power and imported grid power.

Grid Connected systems do not function when there is power outage. When the grid fails, the systems will not operate. But there are new inverters which operate during power outages as long as the load is less than the generated solar power.

Grid Connected inverters can sync with Diesel Generators and help reduce the usage of diesel by up to 50%.
